iRoll Motors is the only source for Panasport wheels specifically made for the Volvo 1800 models in the US. They are 15" x 6" wide with offsets designed for the early ('61 - '69) 1800 bolt patterns. Also for all 122 models (sedan and wagon). They work well with a 195/60 - 15 tire, or a 205. They are one piece, light weight alloy (just over 15 lbs), that increase track and tire footprint all which improve handling. When combined with some high performance shocks (Koni, Bilstein) and springs/sway bar (VPD, IPD) the handling of any 1800 is transformed dramatically. Shipped with center caps.
